TEST METHOD

Bulk is determined by feeding yarn at a constant rate into a fixed-volume chamber, where the filling time is recorded. Titer is measured using the proven Automatic Cut & Weigh principle. Both tests are executed in one seamless sequence, including automatic yarn string-up and removal. Standardized according to ASTM D6587, the system ensures precise and reproducible results.

BENEFITS

• Dual-function testing
  CBW 200 combines bulk and titer measurement in one automated run, eliminating the need for separate instruments and reducing testing time.
• Close-to-production monitoring
  Positioned near the spinning line, CBW 200 enables immediate feedback on yarn quality, helping prevent waste and optimize production efficiency.
• User-friendly operation
  The integrated software allows quick parameter adjustments, automatic data transfer, and long-term result storage—no specialized training required.
• Consistent and repeatable results
  Automatic calibration and self-adjusting pretensioning ensure high reproducibility across test runs, even with varying yarn types.
• Optional automation upgrades
  Enhance efficiency with features like barcode sample identification, Ethernet IP connectivity, and the SESS automatic bobbin changer for multi-position sampling.
